The solution to fix this is to initialize the SCNScene for the trail outside createTrail(color:geometry:). Place this in another Comp and turn visibility off.
However you can use an image sequence or video file or composition where each frame is a different graphic so you could create a comp sequence of the images you want as particles. This is not allowed and may lead to crash The short answer is no you can’t have a different Illustrator graphic for each particle. The problem you're getting an error is that you are initializing the Trail.scn file inside createTrail(color:geometry:) which is called inside spawnShape() which is called inside renderer(_:updateAtTime:), which causes your console to print the following:Ĭode Block Error: Scene is modified within a rendering callback of another scene (). To load a particle system from a file you created with Xcode, use the init(named:inDirectory:) method.
You can attach a particle system to a node in the Xcode scene editor to preview the particle system in your scene.Your artists can work on new particle effects independent of your game code. You separate the task of designing a particle effect from the programming task of using it.Please select a Category below and continue on to the next page to Post a Topic. We also assist customers who purchased Adafruit products through one of our official Distributors. You can experiment quickly with new particle effects and see the results immediately. These forums are for Adafruit customers who need assistance with their purchases from Adafruit Industries.You can easily learn the capabilities of the particle system class.Using Xcode to create your particle systems has a few important advantages:
#PARTICLE PLAYGROUND FORUM ARCHIVE#
Then, at runtime, your game uses this archive to instantiate a new particle system. When complete, Xcode archives the configured system into a file, which you can then include with your project’s bundle resources. As you change the behavior of the particle system, Xcode immediately provides an updated visual effect. Instead, you use Xcode to configure a particle system’s properties. In most cases, you don’t need to configure a particle system directly in your app or game. Use the Xcode Particle System Editor to Experiment with Particle Systems This from the docs may explain why it's gone missing ( emphasis mine) while still being supported ( don't forget to add the SceneKit frwmework).
